Bearpaw Formation, Southern Alberta, Canada
Known also as calcentine or korite, ammonite-derived ammolite is one of several biogenic gemstones, like amber and pearl, and can be grouped with other shell-based marbles such as lumachella, or "fire marble", formed from the fossilized shells of clams or snails. This captivating piece boasts a central burst of orange-red on a ground of golden green, with hints of the rare electric blue color, and measures 2 1/8 x 1 1/8 x 1/8 inches.
